To provide a projector which is designed not to be enlarged.SOLUTION: A projector 1 which modulates and projects light emitted from a light source includes: an outer housing 3 constituting an outer case of the projector; an object to be cooled 5 which is detachably mounted from the outside of the outer housing 3; a cooling fan which supplies a cooling gas to the object to be cooled 5; and a flow path forming member 8 which forms a flow path where the cooling gas supplied from the cooling fan flows. The object to be cooled 5 mounted on the projector forms a flow path with the flow path forming member 8. The cooling gas communicates in the flow path along the object to be cooled 5.SELECTED DRAWING: Figure 12 【課題】大型化を抑制できるプロジェクターを提供する。【解決手段】光源から出射された光を変調して投射するプロジェクター１は、プロジェクターの外装を構成する外装筐体３と、外装筐体３の外部から脱離可能に装着される冷却対象５と、冷却対象５に冷却気体を送出する冷却ファンと、冷却ファンから送出される冷却気体が流通する流路を形成する流路形成部材８と、を備え、冷却対象５は、プロジェクターに装着された状態にて、流路形成部材８とともに流路を形成し、冷却気体は、冷却対象５に沿って流路を流通する。【選択図】図１２
